The impression of the effects of the tips is personal. You clearly don't like the Shure silicone tips but that doesn't mean someone else won't. Personally I only use Comply tips because once inserted they just disappear and their soft material absorbs reflections. Doesn't mean someone else won't prefer something else.

I also like comply but they deteriorate too quickly and they cost far too much (£5 a pair here in the UK )

Solude, are you using the T100 or longer P100?

Currently using large T100. Medium P100 just didn't have enough seal with the 846 and I haven't gotten around to buying another set. They discolour quickly but are easy to clean so a pair usually lasts me six months or so.

T100 looks like the ones that comes with TF10. Never liked those as they change the frequency response. Never liked the foamy kind, they change the sound, I prefer the silicone surface. Like I said, I want silicone tips with bigger bore like the stock complies. Westones comes the closest.

The following cleaning tip is applicable to all MMCX connector in ear monitors (Shure, UE and Westone):

This tip is for those hearing an intermittent drop off of sound from one or both IEMs. Also, I have found it is a good idea every couple of months to clean the connectors to insure optimal performance. You will need DeoxIT D100L Red and DeoxIT Gold (both are available from Amazon) as well as some tissue paper and a couple of toothpicks. Put a small amount of DeoxIT Red on the tissue paper wrapped around a toothpick and gently insert it into the ends of the IEM and cable and twist to clean the connector. Then repeat this with the DeoxIT Gold. Let them dry for 30 minutes or so and reconnect the cable to the IEM and you are finished.

846 definitely separates the vocals from instrumentation. It sounds like there is a layering with it. Vocals layered out, and others behind. Some iems they are on the same layer so voice gets over powered, but the 846 you hear a clear distinction. I think this is Shure signature and I can see why people would like it as soon as they start listen, as it hits you since it is distinct. It provides imaging as there is a separation that is noticeable. Only problem with this method is you notice a limited band of the strongest sound and rest that adds to soundstage is in the background, but since the strong part creates the shape of the sound as a whole, sound is perceived as being less wide than other headphones where all the sounds are in one layer. But still has wider presence than what 535 provides.

Are there any other US online retailers that give a good deal for these IEMs? Amazon has it for sale for $999.00. Thanks!

Edit: Was looking at Spectrum Audio as recommended a few posts back and from another forum member. Is this an official Shure reseller? I just want to make sure I'm covered by Shure's warranty before pulling the trigger.

I agree on the whole layer part, 846 has layers after layers and I have listen enough universal IEM to come to the same conclusion, and because the vocal kinda of pop out, it starts to creates a 3D dimension as compare to say EX1000 which is really wide but more on the same layer with rest of instrument. Since I love vocal jazz to death, it works 99.9% of the time. In Vocal Jazz, I luv the attention given to the vocal, and with 846 good sense of depth, it not only has good placement of each instrument, but also creates an illusion of distance from the listener. I have not listen to CIEM yet so my limited perspective is just universal IEM and shure 846 is about the best of them all besides TG 334. One quality that 846 has that most other UIEM fails to create, is the sense of space behind the listener.

The problem with this method as mention above is the greatest strength of 846 IMO. There are so many cheaper headphones out there and even some flagship headphones with a slight U shape frequency to enhance the extreme ends of the frequency to fit into the modern pop music. There are tons of the these out there but only a few handful boutique audiophile headphones that does justice to the vocal and they are expensive like the TG334, LCD-2, LCD-3, W3000, Stax 009, K3003 et al. These headphones/ IEM have the "vocal pop" similar to 846 IMO. I do love those vocal stand out of the above phone and never find them to overpowering the rest of the frequency.

Questions: Do you find those headphones having the same effect as 846 of vocal standing out and making the instruments becoming background?

I read westone is coming with a 1000 dollar IEM. Should I cancel my order and wait what Westone will bring to the table?

I believe the W60 was announced at CES 2014 but there have been no updates that I know of since. If you really really like the sound of the SE846 my advice is that there's no harm in picking up a set until you can do a comparison with the new Westones, then figure out what to do from there.
